Question Asked: 

Recently while idleing at stop after travelling for some distances, my 3.1L V6 Chevy engine stumbled or stalled, but did not quit or die. There was also metallic clicking noises during stalling! The engine OBD I scanner showed trouble codes 37 (TCC brake switch stuck "ON") and 82 (3X crankshaft position sensor signal error). Since the clicking noise sounded like EGR's solenoid clicking, and engine stumbled or stalled, can any of these codes cause the EGR's solinoid clicking and intermitten opened? Thanks for your advice!

Question Asked: 

My chevy 3.1L V6 95 engine recently has high-idle RPM ( about 1500), which last unusually long time, after the engine got first started in the morning after an over-night park. After that, the idling RPM seems fine. Prior to this, the first start-up idle RPM sometimes fast settled to normal RPM, but sometimes slower. The IAC valve's terminal resistances has been checked okay according to a specification. And the morning temperature has not varied much! Your feedback is appreciated!
